Knodishall, a village in Suffolk, England, lies 3.5 miles (6 km) south-east of Saxmundham, 1 mile (2 km) south-west of Leiston, and 3 miles from the coast, in the Blything Hundred. Most dwellings are now at Coldfair Green; just a few remain in the original village by the parish Church of St Lawrence, which falls gently on the north side of the Hundred River valley. It is now an outlier of Knodishall Common, a settlement a mile to the south-east. The estimated parish population was 790 in 2019.
